HOl STlNG-BUCKET.

SPECIFICATION forming part of Letters Patent No. 302,152, dated July 15,1884.

Application filed June 3, 1884.

To aZZ whom, it may concern/:

Be it known that we, GEORGE H. MILLER and OASIMIR GoYE'r'rE, ofPawtucket, in the county of Providence'and' State of Rhode or otherplaces of deposit; and the object of our invention is to facilitate'theopening and closing and also the raising and lowering of the bucket.

To the above ends our invention consists in certain peculiar features ofconstruction and arrangement of the bucket-and certain of its operatingconnections, as hereinafter described and claimed.

In order that our invention may be fully understood, we will proceed todescribe it with reference to the accompanying drawings, in which Figurel is a general side view of ourimproved bucket and its operativeconnections. Fig. 2 is a perspective view of the bucket in closedposition. Fig. 3' is a top view of the same in open position.

In the said drawings, AA designate the two halves of the bucket. side ofthe section A extend upwardly the two movable arms B B, each of which isconnected pivotally at its lower end to the side of the section, whileat their upper ends said arms are pivoted to a cross-bar, I). From theinner side of the section A extend upwardly two rigid arms, 0 O, whichare pivotally con-- nected by the cross-bar c. From. the outer side ofthe section .A extend upwardly two movable arms, B B, the lower end ofeach of which is pivotally connected to the side of the section, whiletheir upper ends are attached pivotally upon the cross-bar Z). From theinner side of the section A extend upwardly two rigid arms, 0 O, whichare pivotallyconnected to the crossbar c. I The arms 0 are in reality asingle bar of iron, which is bent in U form, and the ends of which aresecured rig- From the outer (No model.)

points 0 of the bar 0, upon which the arms 0- O, are pivoted, are inreality the hinges upon which the two sections of the bucket-move whenthe bucket is openedor closed. The upper end of each of thearms C isbent laterally, as shown at D, and the outer ends of the two extensionsD are connected by a cross-bar, d, which carries two pulleys, c. Uponthe arms G" are mounted two bars or brackets, D, the upper ends of whichare connected by the cross-bar d, and these brackets carry the drum E,which consists of a central section separated from an outer section uponeither side by two circular flanges, as shown in Fig. 3.

idly to the inner sides of the section A. The I hollow and provided withan aperture in its top. The stop F is also provided with twodownwardly-extending pieces, f, through the lower ends of which thecross-bar 12 passes.

G designates the hoisting-line, which passes downward through the stopF, and thence around the central portion of the drum E,*to which thelower end of the line is secured. g g designate the two winding-lines,each of which is attached at its upper end to the cross-bar d,and'passes thence over one of the pulleys e, andthence to one of theouter portions of the drum E, where the lower end of the chain issecured.

H designates the derrick-boom, the outer I endof which is held to thederrick-mast by the usual stays, h h. At its outer end the boom Hcarries a pulley, h, over which the hoistingline-G passes to thehoisting apparatus.

Idesignates a ring which is suspended horizontally from the boom '11 bythe chainsor cords z, and this ring carries the freely-swingingcatch-hooks-i" i, two or more of which may be employed. The catches 03are connected by a branched line, i which passes over pulleys h securedto the boom, and this line passes downward along the boom and mast to jthe station of the operator; The catches 4; may be weighted, asillustrated in Fig. 1, so

as to insure their retention in proper position and their effectiveoperation.

Patentmanner that when the bucket is opened the I catch shall engagewith the cross-bar d and hold the bucket in open position.

The operation of the above-describedmechanism is as follows: For thepurposes of this description let it be supposed that the parts are inthe positions shown in Fig. 1, the bucket having discharged its load andbeing held in open condition by the catch A. The bucket is lowered bypaying out upon theline G until it (the bucket) strikes the mass of coalto be hoisted. The catch is now thrown off of the crossbar d and thelineG is hauled in,wl1ereby the bucket is closed in consequence of therevolution of the drum E, produced by the line G and the winding of thelines {I 9 upon said drum. After having been thus closed the bucket ishoisted up in closed condition by the line G till the stop F has passedbetween the catches i, which will then automatically engage beneath thelower edge of the stop F. The line G is then paid out and the bucketwill open, owing to the reverse movement of the drum E, the bucket beingheld suspended by the stop F and catches i. As soon as the bucketassumes the wide open condition illus trated in Figs. 1 and 3 the catchA grasps the bar (1 and holds the bucket open. The bucket is now raiseda little by hauling on the line G, when the branched line i is hauledupon, so as to separate the catches i from the stop F. The line G isnowpaid out and the bucket descends again to the pile of material, alterwhich the above-described operations are repeated.

e do not wish to be understood as confining ourselves to the precisedetails of construction and arrangement above described, be cause ourinvention contemplates various modifications of such details. Forinstance, the form of the catch A, as shown, is only indicative of itsfunction, and we propose to employ any form of catch which will hold thebucket open and permit of being released at the proper time. \Ve alsointend, if desired, to substitute for the ring I a conical piece similarto the piece F, so that no defect in the operation of the catches i mayoccur, and we contemplate other modifications of details. Therefore werefer to the claims for an ascertainment of our invention.

Having thus described our invention, we claim as new and desire tosecure by Letters 1. The combination,with a hoisting-bucket constructedsubstantially as described, and provided with a stop, of a catch orcatches attached to the boom, and arranged to automatically grasp thestop, so as to hold the bucket in suspended condition during the'ooopening of the same, and connections for releasing the catches from thebucket when the .same is to be lowered, substantially as set forth.

2. The combination,with the bucket having The combination of the ring I,the catches and the branched line i, substantially as set forth.

4-. The combination, with the derrick-boom carrying the pulleys h, ofthe ring I, carrying the catches i, the chains 42, and the branched line11, substantially as described.

5. The bucket-section A, provided with the arms B O and the cross-bars bc, in co1nbination with the section A, provided with the arms B O andthe extension D, thebrackets D, the cross-bars d d, and the drum E andpulleys a, substantially as specified.

(5. The bucket-section A, having the catch A and the arms B C, andcross-bars I) c, in combination with the section A, having the arms B G,the extension D, the brackets l), and the crossbars d d, substantiallyas set forth.

7. The co1nbiuation,with the bucket having the arms B 3 G C, theextension D, the brackets D, and the cross-bars b c d d, of the stop F,having the extensions f and the drum E and pulleys c a, substantially asdescribed. 5

8. The combination of the boom carrying the pulleys It h, the ring I,having the catches vi, the chains 2', the branched cord and the bucketconstructed as described, and having the stop F, catch A, drum E,pulleys e c, and line G and chains 5 as set forth.
